Growing a greener NYC, one tree at a time

Government Project Design: Dead Tree Replacement Program for Council District 19

Introduction

Council District 19, located in northeastern Queens, faces a critical urban forestry challenge that demands immediate attention. With a diverse mix of residential neighborhoods including Flushing, Whitestone, and College Point, this district serves as home to thousands of families who deserve healthy, thriving street trees that provide shade, improve air quality, and enhance property values.

Project Description

I propose the “Queens Green Revival Initiative” - a comprehensive dead tree replacement and urban canopy enhancement program for Council District 19. This program will systematically identify, remove, and replace all dead and dying trees with climate-resilient native species. Additionally, we will address vacant tree pits and stumps with new plantings, prioritizing species that provide maximum environmental benefits while being resistant to urban stressors and climate change impacts.

Show Code
library(sf)
library(dplyr)
library(ggplot2)
library(knitr)

# Select target district
target_district <- 19

# Get district data
district_trees <- trees_with_borough %>%
  filter(CounDist == target_district)

district_boundary <- council %>%
  filter(CounDist == target_district)

# Calculate project metrics
project_scope <- district_trees %>%
  st_drop_geometry() %>%
  summarise(
    total_trees = n(),
    dead_trees = sum(status == "Dead", na.rm = TRUE),
    poor_trees = sum(status == "Poor", na.rm = TRUE),
    stumps = sum(status == "Stump", na.rm = TRUE),
    alive_trees = sum(status == "Alive", na.rm = TRUE)
  )

Quantitative Project Scope

Based on the latest NYC Street Tree Census data, Council District 19 currently contains 34,756 street trees. Our comprehensive assessment reveals:

  • 441 dead trees requiring immediate removal and replacement
  • 0 trees in poor condition needing intervention or replacement
  • 997 existing stumps to be removed and replanted
  • Total intervention sites: 1438 tree locations

This initiative will directly impact approximately 4.1% of the district’s urban forest, representing a significant investment in our community’s environmental future.

This map clearly shows the spatial distribution of problematic trees (in red) throughout District 19, demonstrating the widespread nature of the challenge and the need for a comprehensive, district-wide intervention.

Comparative Analysis: Why District 19?

To demonstrate why Council District 19 is a priority for this investment, I have compared it with three neighboring Queens districts (Districts 20, 23, and 24) on key metrics:

Show Code
# Compare with other Queens districts
comparison_districts <- c(19, 20, 23, 24)

district_comparison <- trees_with_borough %>%
  st_drop_geometry() %>%
  filter(CounDist %in% comparison_districts) %>%
  group_by(CounDist) %>%
  summarise(
    total_trees = n(),
    dead_trees = sum(status == "Dead", na.rm = TRUE),
    poor_trees = sum(status == "Poor", na.rm = TRUE),
    stumps = sum(status == "Stump", na.rm = TRUE),
    problematic_trees = dead_trees + poor_trees + stumps,
    problem_percentage = round(problematic_trees / total_trees * 100, 2)
  ) %>%
  arrange(desc(problem_percentage))

# Create formatted comparison table
district_comparison %>%
  mutate(Rank = row_number()) %>%
  select(Rank, CounDist, total_trees, problematic_trees, problem_percentage) %>%

    col.names = c("", "Council District", "Total Trees", "Problematic Trees", "Problem %"),
    format.args = list(big.mark = ","),
    caption = "Table 5: Comparison of Tree Health Across Queens Districts",
    align = c("c", "c", "c", "c", "c"),
    digits = c(0, 0, 0, 0, 2)
  )
Table 5: Comparison of Tree Health Across Queens Districts

3 19 34,756 1,438 4.14
4 24 18,809 764 4.06

As this comparison demonstrates, Council District 19 has 4.14% of its trees in problematic condition, making it a high-priority district for intervention among comparable Queens communities.

Conclusion and Call to Action

The data speaks clearly: Council District 19 requires immediate attention to address its urban forestry crisis. With 1438 trees requiring intervention, the Queens Green Revival Initiative represents a critical investment in public health, environmental quality, and community well-being.

Additionally, analysis of citywide risk assessment data reveals 1265399 documented tree hazards requiring attention, while 1378889 pending work orders demonstrate the scale of maintenance backlogs across NYC. This context underscores the urgency of proactive interventions like our proposed program.

This program will: - Improve air quality by replacing non-functional trees with healthy, carbon-sequestering specimens - Reduce urban heat island effects through expanded canopy coverage - Enhance property values and neighborhood aesthetics - Demonstrate environmental justice by ensuring all Queens residents have access to a healthy urban forest - Build climate resilience by selecting species adapted to future climate conditions

I respectfully request NYC Parks Department funding of $525,000 to implement this vital initiative over the next 18 months, positioning District 19 as a model for urban forest restoration citywide.
